Texbox to Textbox?

This must be a stupid question, but after an hour of trying it's now intelligent for me to ask.

How would I sync a form's textbox, with the main form's textbox?

When the user, click a button on the main form, another form loads up.
Then when they change the textbox, I want a textbox in the main form to be updated with that string. Simple right!

In the old VB6, this was completely trivial.
It seems that .NET is not as easy, perhaps for protection?
I tried delclaring the form, and texbox, but to no avail.


At a loss,
TT(n)

Does the main form get updated when the user clicks a button to close it? It should be easy to do that.

This is the code on the main form

VB Code:

Private Sub Button1_Click(sender as System.Object, e as System.Eventargs) Handles Button1.Click
   Dim NewFrm as New Form2
 
   NewFrm.TextBox1.Text = TextBox1.Text
   If NewFrm.Show = DialogResult.Ok Then
      TextBox1.Text = NewFrm.TextBox1.Text
   End If
End Sub

Thanks, but no, when it get's changed. I thought I was clear on that
Your example didn't seem to work either.

This is the event I want to update the main form with.
This event is in the form, that was loaded by the main form.

VB Code:

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
 
'how to update the main form's TexBox2.text, with the contents of TextBox1.text
 
End Sub

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim fr As New Form1
        AddHandler fr.TextBox1.TextChanged, AddressOf ChangeHandler
 
        fr.Show()
    End Sub
 
    Private Sub ChangeHandler(ByVal sender As Object, ByVal e As EventArgs)
        Me.TextBox1.Text = DirectCast(sender, TextBox).Text
    End Sub

Thank a centillion!
